Question

Paheli prepared a blue coloured solution of copper sulphate in
beaker A and placed an iron nail in it. Boojho prepared a yellowish
green solution of ferrous sulphate in beaker B and placed a copper
wire in it. What changes will they observe in the two beakers
after an hour?

Answer 1

Answer:

In beaker A reaction takes place place because according to reactivity series, iron is more reactive than copper, so iron displaces copper from its solution

In beaker B no reaction takes place as ferrous sulphate(iron) is more reactive than copper and thus copper would not displace iron from its solution

hope this helps
